Be. il; lmpwn that l; ARTHUR E. MILLiNG- TON, a sit/fen 0f thi-w ntfwil States, resid' in Espanola, Ontario,4 Canada, have invenl certain Improvements in Paperfarrng pf para/sub1, n'f which the llgw'hg n speccation.

One abject of 'my monjbion is to l[,jzmflld a machine for applying im; tu a continuous strip lof papel in suc-l manner that the suc cessvf. :were of i319 finished. tamed paper will not stick ta'agether when in the form of xx roll.

Another obeext of the invention is to pm# vde a. relatively :simple and yet efzient com bnation of parts. for applying tar to a continuous strip oil paper, which apparatus shallY be so cvnsllruvted am zurnge as in require a minimum nl' etlxim xml hbox' for its successful operativa i t5 I attain as hereinafter svi, i'urfl, raler@ e being had t0 thfi icnrol'npmlyng drawings, 'm wlitlm- Figur@ l is :L Hifo elvvalnxl @l mv paperaxring nppul'zatua, Slwm'ng in venti-zal scf-,- lion the inivriur nl the i1:if-ffmmlrinngg tank.

Y ive tl'w-iqieazn-ulls, I pro- Sppmtml in bearings un the -uure B and on the stemdzu'd i" and vfled with fast and lm'mv pullu f* 211111103, there being upon said shaft 'in aflditqh a pulley-wheel j and a. pinion f5. Masking with this pinion is @gear-wheel a5, carried on one end of the supurhugml of the squeezcroll e', while on the Gp'pnSite mld ofsaid shaftearwheel f5', fixed In hm adj minut and of the haft nl: squezv-nilll :A figlia-nent tu the end of the structure B, upon whicflyjflm squeeze-'ms areV lis carried, is a fr'alne having bearings for a air of spindles g and g', upon which are oosely carried tubular spindles y, rapa ble of being operatively connected lo their respective supporting-shafts by clutch mechanism q. The shafts themselves are dii-evtl y driven ymeansof earing, (shown indotted lines in Fig. 1,) Whic in turn is actuated throu rh the medium of a belt ",passing over the pu ley f on the' shaft f. r uitable braking means for the tubular siindles ga is provided, as indicated at g, 1t being understood that said means may be a plied to that one of the two shafts g from -w ich paper is being unwound to control the tension thereof.

Preferably carried 4upon the 'same foundation as that sup ortin the frame G is a paper-slitting macfiine I and beyond this is a winding device consistin of a pair of spindles J, supported on the sha t j, on which is carried the roller j for the reception of twol or any desired number of rolls of paper, this shaft being driven by means of power applied to a pulley-wheeljz'. y

In order to operate the machine, a roll of paper to be tarred, as X, is placed upon the shaft a of the frame a and the paper web is drawn from this roll over the gu1de-roll b. The frame D bein raised to the upper art of the frame C, said' web is passed un er the roller d', between the Scrapers b5 and b?, over the guide-roll b", and betweeny the squeezerolls e and e', and bysuitable manipulation of the crank-handle c* said frame D is lowered until the roller d is practically at the bottom .of the tank d. The tar in said tankbeing heated to a suitable temperature, the paper is drawn from the roll' X through the said tar and after passing through said 'squeeze-rolls is wound upon a tubular shaft carried by one of the spindles g or g.

It will be understood that the braking means a is adjusted so`as to cause the pa er web to have a proper tension, and in a dition the squeeze-rolls are pressed together, so as to exert the desired pressure upon the web as it passes between them, so that the tar is pressed into the fibers of the paper to such au extent th at i't may be safely wound into a roll without the separate layers sticking together. In order to insure the layers of this tarred pa'- per from sticking together at any future time, place the completed re'l f -i the spindle g and cause it to be unwoen by the action of the receiving-roll j upon the shaft j, which draws the web through theslitting-machine H and winds its different sections into rol'l's of commercial size, tliere being another roll of paperI under process of formation on the npper spindle. i

It will be seen that after assing into the tar'bath the web of paper is i rawn vertically out of the same and while being so moved is engaged by-the Scrapers and b", which re- .move the greater portion of the snlmfluous tar from it. There is in addition an auxiliary scraper 67, which removes a further quantity of tar from the web before it passes to the squeeze-rolls e arid e', which latter naturally cause another portion ofthe still liquid tar to be expressed from the paper.

For the purpose of collecting these various bodies of tar I referabl rovide an inclined extension at tie end o die tank b, as indicated at b, whereby the tarrernoved by the Scrapers and squeeze-rolls may be directed back into the said tank. i

It will be further noted that Vthe squeezerolls so press the tar into the fibers of the paper that it is not only free from sticki less to such an extent as to allor* of its being wound in a roll without the layers adhering to each other, but in addition after it has once been unwound from said roll and rewound the layers of the finished rolls have no tendency at any time to stick together. Hitherto from twentyffivc to thirty' per cent. of the rolls of tar-paper supplied to the trade have been found to be practically worthless because of the stickin togetherof their la ers, and I have found t iat after paper has en tarred in the above machine andVV then unwound and ,rewound said stickin has been absolutely avoided, even though t 1e finished pa er be stored for long periods of time. l

he mere passage of paper through a tarbath and between the squeeze-rolls, followed by immediate winding, has not been found to secure lthe above-noted advantageous results, since it has been found lthat on unwinding for use a large number of rolis invariably were rendered useless, owing to the sticking together of their various layers. If, however, paper be unwound from its primary roll, so as to be fully ex osed to the air, and then rewoulrd, the ob]ectionable and destructive sticking `above notedis revented.

Another ihcidental advantage ofl this process of treatment is due to the fact that a double sheet seventy-two inches wide is handled in one operation-that is, the wide sheet is passed through the tank and while bein unwound from its rimary roll is cut into s leets and then wound)in small rolls ofcommereial size.

I claim as my inventionf.

1. The process of preparing tarredipa er, A

which consists in assing a continuous we of Ilo paper through a )ody oi' tar, subjecting the coated paper to relatively high ressnre to force the tar into and through t e fibers of the same, Winding said paper in a roll, then unwindiug the aper so that it is exposed Ito the air and finally rewinding said paper, substantially as described.

2. In avmachine for tarring aper, the combination ol a tank, a guide-ro l 1n said tank, means for directing a paper web into the tank to said guide-roll, and means for directing the web in a substantially vertical line from Sia Gf lh'ikfebbe'fore it passes Lo tha squeezerls, substantially as described.
